NOVUS N480I - Manual

5.1 ALARM INITIAL BLOCKING
Alarm blocking at power-up inhibits the relay alarm to trip when the unit is first energized. The alarm will only
trip after the process variable reaches a new alarm situation.
Error alarm shows sensor defects or not properly connected.
6 PROBLEMS WITH THE CONTROLLER
Connection and configuration errors state for most of the problems in using the controller. A final revision of
parameters will save time and further losses.
Error messages are displayed to help the user to identify possible problems.
: Process temperature is below the selected sensor range.
: Process temperature is above the selected sensor range
Erro : Controller or sensor error. Example: Broken thermocouple or Pt100. Pt100 badly
connected, short-circuited or high cable resistance.
6.2 ELECTRONIC SERIAL NUMBER VISUALIZATION
To read the 8-digit serial number go to the Operation Level and press the key for 3 seconds. The display
will show the first 4 digits. Then keep the key pressed for 3 seconds and the display will show the last 4
digits.
FIRST 4 DIGITS
SERIAL NUMBER
LAST 4 DIGITS
When powering the unit the display will show the software version for a few seconds.
7 PRODUCT IDENTIFICATION
The label attached to the controller case identifies the model and the optional present in the product, as
described below:
MODEL: N480I – A – B, where:
A: Outputs: RP OUT A = Relay and OUT B = Relay
RF OUT A = Relay and OUT B = 24Vdc auxiliary supply
B. Voltage rating: blank (100-240 Vac/dc) or 24V (24 Vac/dc)
8 TECHNICAL ASSISTANCE
If you encounter a problem with your controller, review the configuration with regard to inputs, outputs,
alarms, etc. If the problem persists, contact your supplier or Novus at [email protected].
